  • List of all tickets closed : Changelog

  Piwik 2.1 is the first release after our 2.0 release and it reflects the new direction Piwik is moving in : better performance, more reliability and a better overall open platform ! We also released more plugins on the marketplace as well as helped developers build exciting new plugins for Piwik.

  This 2.1.0 release contains several performance and reliability improvements to the archiving process and to the new device detection process introduced in Piwik 2.0. It also includes a new email report format (CSV), a new marketplace plugin and overall more than 80 improvements (source).

  Massive Performance Improvements to Archiving

  The biggest improvement this release brings to Piwik are the various performance improvements made to the Archiving Process. These improvements include the following :

  • The amount of memory used has been reduced in some cases by 80% or more ! What used to require 8GB of memory will now only require 1GB. Piwik engineers analysed Profiler XHProf reports of Piwik under high load and implemented several improvements to archiving.
  • The cron script you can setup to automatically process your reports will now create new processes to perform asynchronous archiving instead issuing CURL http requests. This change results in increases to the performance and reliability of the Archiving Process.

  Bug Fixes and Performance Improvements to Device Detection

  In Piwik 1.12 we introduced a new device detection feature that could detect much more information than what we used before. Piwik 2.1 includes several bug fixes and improvements to this feature (such as detecting dozens of new devices, brands and models for smartphones, tablets and other devices). To use this feature, go to “Settings” then “Plugins” then activate the DevicesDetection plugin.

  New Default MySQL Database Type (InnoDB)

  This change doesn’t affect our existing Piwik users, but it does reflect our commitment to performance and reliability. We’ve changed the default MySQL database type to be InnoDB instead of Myisam. This will allow new users to immediately gain the benefits in reliability offered by InnoDB.

  New Marketplace Plugin – HTTP Authentication

  We’re releasing a new plugin on the marketplace that will allow you to use the HTTP authentication services provided by your webserver. Learn more about this plugin on the marketplace.

  New Email Format for Scheduled Reports

  The last big change in this release is a new email report format. You can now get your email reports as CSV files as well as HTML and PDF reports.

  Other Improvements

  In addition to performance improvements and new plugins, this release contains a few other smaller improvements described below.

  Changing segments in the Embedded Dashboard

  The embedded dashboard is the powerful feature that lets you include the Piwik Dashboard without the top menu and Piwik branding, directly within your application !

  This dashboard will now include the segment selector allowing you to change the current segment and create new segments, just as you would in the normal dashboard view :

  

  Multiple Super Users

  It’s now possible for your Piwik to have more than one Super User and for Super Users to have aliases :

  

  Learn more in the User guide : Managing Super Users in Piwik.

  Smart App Banners for our Mobile Apps

  Finally, in accord with our commitment to providing great User Experience, we’ve added a smart banner to Piwik so users that view Piwik from a mobile device will be informed of our amazing (and free !) mobile apps (for both iOS and Android).

  Thank you to the core developers, all the beta testers and users, our official supporters, the translators & everyone who reported bugs or feature requests. Also thank you to the software we use, and the libraries we use.

  Many of the improvements in this release come from the efforts of Piwik PRO experts. If you are looking for help to make the most of your analytics data, contact Piwik PRO. Learn more about us here.

• avcodec : add DFPWM1a codec

  8 mars 2022, par Jack Bruienne

  avcodec : add DFPWM1a codec
  From the wiki page (https://wiki.vexatos.com/dfpwm) :
  
  > DFPWM (Dynamic Filter Pulse Width Modulation) is an audio codec
  
  > created by Ben “GreaseMonkey” Russell in 2012, originally to be used
  
  > as a voice codec for asiekierka's pixmess, a C remake of 64pixels.
  
  > It is a 1-bit-per-sample codec which uses a dynamic-strength one-pole
  
  > low-pass filter as a predictor. Due to the fact that a raw DPFWM decoding
  
  > creates a high-pitched whine, it is often followed by some post-processing
  
  > filters to make the stream more listenable.
  It has recently gained popularity through the ComputerCraft mod for
  
  Minecraft, which added support for audio through this codec, as well as
  
  the Computronics expansion which preceeded the official support. These
  
  both implement the slightly adjusted 1a version of the codec, which is
  
  the version I have chosen for this patch.
  This patch adds a new codec (with encoding and decoding) for DFPWM1a.
  
  The codec sources are pretty simple : they use the reference codec with
  
  a basic wrapper to connect it to the FFmpeg AVCodec system.
  To clarify, the codec does not have a specific sample rate - it is
  
  provided by the container (or user), which is typically 48000, but has
  
  also been known to be 32768. The codec does not specify channel info
  
  either, and it's pretty much always used with one mono channel.
  
  However, since it appears that libavcodec expects both sample rate and
  
  channel count to be handled by either the codec or container, I have
  
  made the decision to allow multiple channels interleaved, which as far
  
  as I know has never been used, but it works fine here nevertheless. The
  
  accompanying raw format has a channels option to set this. (I expect
  
  most users of this will not use multiple channels, but it remains an
  
  option just in case.)
  This patch will be highly useful to ComputerCraft developers who are
  
  working with audio, as it is the standard format for audio, and there
  
  are few user-friendly encoders out there, and even fewer decoders. It
  
  will streamline the process for importing and listening to audio,
  
  replacing the need to write code or use tools that require very
  
  specific input formats.
  You may use the CraftOS-PC program (https://www.craftos-pc.cc) to test
  
  out DFPWM playback. To use it, run the program and type this command :
  
  "attach left speaker" Then run "speaker play <file.dfpwm>" for each file.
  
  The app runs in a sandbox, so files have to be transferred in first ;
  
  the easiest way to do this is to simply drag the file on the window.
  
  (Or copy files to the folder at https://www.craftos-pc.cc/docs/saves.)
  Sample DFPWM files can be generated with an online tool at
  
  https://music.madefor.cc. This is the current best way to encode DFPWM
  
  files. Simply drag an audio file onto the page, and it will encode it,
  
  giving a download link on the page.
  I've made sure to update all of the docs as per Developer§7, and I've
  
  tested it as per section 8. Test files encoded to DFPWM play correctly
  
  in ComputerCraft, and other files that work in CC are correctly decoded.
  
  I have also verified that corrupt files do not crash the decoder - this
  
  should theoretically not be an issue as the result size is constant with
  
  respect to the input size.
